Irmengard of Oettingen

Irmengard of Oettingen (c. 1304–1389) was a daughter of Count Louis VI of Oettingen and Agnes of Württemberg. In 1320 she married Adolf the Upright, nominal Count Palatine of the Rhine; his uncle Emperor Louis IV exercised the actual power of government, and Adolf died in 1327.

After his death she retired to the Dominican Liebenau monastery at Worms; the Treaty of Pavia in 1329 secured her young son Rupert II's succession to the Palatinate. She took the veil around 1347 and died at Liebenau in 1389.
